Answer:
No, it is not a right triangle.
Step-by-step explanation:
The simplest way to determine is testing out the numbers with Pythagorian theorem.
If it complies with the theorem, it is a right triangle.
let's assume c = 28, b = 21, and a = 20
the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.
According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.
check:
c^2 = 28^2 = 784
a^2 + b^2 = 21^2 + 20^2 = 841
because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.
Answer: (x–2) and (10x+7)
Step-by-step explanation:
10x^2 – 13x – 14=
10x^2 – 20x + 7x – 14=
10x(x–2) + 7(x–2)=(x–2)(10x+7) ==> 3rd option
6) p = 3.95 + 0.85t
7) e= 7.25n
8) p = 30 + 12w
9) f = 75 + 60h
10) d = 1 + 0.5h
11) j = 3x - 3, j = 3(5) - 3, j = 12
12) r = 4.25 + 1.50m
When m = 12, r = 4.25 + 1.50(12)
r = 4.25 + 18
r = 22.25
